Launch Angle Standard Deviation as a Performance Indicator

Updated: Sep 14, 2020

Here's a quick project I took on this afternoon. I wanted to look at the correlation between the standard deviation of a hitter's Launch Angle and their offensive performance (wRC+). There is a negative correlation in that as the deviation gets smaller wRC+ increases.

Here is the full list of hitters with their Average Launch Angle, STD, and wRC+ for 2018.

Obviously, we can see having a smaller deviation in launch angles is beneficial, but so too is the actual angle where the hitter is hitting the balls.
